DNA, RNA, and Snorks Teacher Guide

Original Document: DNA, RNA, and Snorks

This activity can become tedious if you assign all of the snorks. It is recommended that you assign only one (possibly) two for students to decode. Their sketches can be creative and likely none will be the same, the key below shows you the traits that each snork should have based on the codons and amino acid sequence. You may also wish to do the first one on the overhead projector to show students how to construct their snorks.
